BUILDER-MOTION FOE SPINNING-FRAMES.

Specification of Letters Patent.

Application filed December 15, 1916.

To all whom it may concern:

Be it known that I, ALoNzo E. Ri-ioAnEs, a citizen of the United Statesresiding at Hopedale, county of lVorcester, State of Massachusetts, haveinvented an Improvement in Builder Motions for Spinning- Franies, ofwhich the following description, in connection with the accompanyingdrawing, is a specification, lik characters on the drawing representinglike parts.

This invention relates to improvements in builder motions for spinningframes especially of the type which are adapted to wind filling carriersprovided with feeler slots near the base thereof.

In the Case of filling carriers of this type a feeler enters the slot inthe filling carrier when the filling exposes the portion of the slot tobe thus entered and this action is utilized to effect a change in theloom operation such as the replenishment of the shuttle with a freshfilling carrier. It is desirable therefore that a suiiicient amount offilling be wound upon the base of the filling carrier beneath thatportion of the slot entered by the feeler to allow for one or more picksthrough the loom and a sufficient anchorage of the filling end on thefilling carrier to prevent the filling end from being drawn OE andcurled up during the last pick of the loom before transfer takes place.

The object of this invention is to provide means for laying the requiredamount of filling upon the filling carrier below the por tion of theslot to be entered by the feeler during an upward and downwardpreliminary traverse.

The object of the invention further is to lay upon the filling carrierbelow the portion of the slot to be entered by the feeler during thepreliminary upward and clownward traverse substantially such an amountof filling as would be laid during a full or complete upward anddownward traverse.

The object of the invention is further to provide means for adjustingthe point in the first upward traverse at which the laying of fillingupon the filling carrier shall begin.

These and other object of the invention will appear more fully from theaccompanying description and drawings and will be particularly pointedout in the claims.

While the invention is applicable to various types of spinning frames itis shown in Patented Feb. as, 1918.

F ig. i is a top plan view of the parts shown in Fig. 3 with the frameomitted;

Fig. 5 is a *iew similar to Fig. 3 with the frame omitted and with theparts shown in position at the conclusion of the first upward traverse.

The general construction of spinning frames of the various types and ofbuilder motions is so well known and familiar to those skilled in theart that no detailed description of the parts not immediately concernedwith the present invention need be given. As already pointed out theinvention is applicable to various types of spinning frames and forconvenience of disclosure a spinning frame of the ring type isillustrated.

The frame of the machine comprises the side pieces the left hand one 1of which is shown. The longitudinal ladder or box rail 2 extendstransversely between the side frames and in it are mounted and driventhe spindles 3 upon which are placed the filling carriers at. The usuallifter rail 5 upon which are mounted the rings 6 with their travelers issupported by the lifter rods one of which is shown at 7 and which areguided vertically in the ladder or box rail 2. Each lifter rod 7 isprovided at the lower end with a foot piece 8 resting upon a roller 9carried by an oscillating lever 10. The oscillating levers are connectedby the rod 11 and the left hand lever 10 is connected by a chain 12running over a sheave 13 to the builder motion. The builder motion actsto depress the lifter rail 5 by pulling upon the chain 12, the lifterrail being depressed by its own weight. As the builder motion lets offthe chain 12 suitable weights connected with the levers 10 cause theelevation of the lifter rail 5. Thus the filling is laid on the fillingcarriers by an up and down traverse of the ring rail with respectthereto.

The builder motion illustrated is of a generally familiar type. Itincludes a builder cam 1% mounted on a shaft 15 and driven by suitableconnections, not illustrated, in the direction of the arrows in Figs. 3and 5. This cam cooperates with a follower 16 carried by a stud 17projecting laterally from the builder arm 18 pivotally mounted at oneend on a stub shaft 19 secured in the frame. The builder cam is providedwith a plurality of lobes each of which acts to give a complete traverseto the lifter rail. One side 20 of each lobe acts to give the clownwardtraverse and the other side 21 the upward traverse.

A second or shifter arm 22 is pivotally mounted on a shaft 23 carried bythe builder arm 18, a projection 24 extending from the opposite side ofthe builder arm to provide a suitable support for the said shaft. Thepivot for this shifter arm is located intermediate the builder cam andthe pivot of the builder arm. The free end of the shifter arm itselfextends well beyond the free end of the builder arm.

The usual pick motion by which gain is imparted to the traverse ismounted on the shifter arm. This pick motion comprises a ratchet wheel25 actuated by a pawl 26 on a carrier 27, the carrier receiving itsmotion from a rod 28 connected thereto and provided with adjustablecollars 29 which engage a fixed portion 30 of the frame as the ratchetwheel and pawl carrier are bodily reciprocated vertically in the usualmanner. The ratchet wheel 25 is mounted on the end of a shaft 31journaled in bearings 32 and 33 depending from the shifter arm 22 andcarries at its rear end a worm 3 1 engaging and operating a worm gear 35mounted on the shaft 23. The worm gear 35 has attached thereto a drum36. The chain 12 after passing over the sheave 13 passes down around asheave 37 journaled on the shifter arm 22 at a point intermediate itspivot and its free end and then passes to the drum 36 to which it isattached and upon which it is wound up and let off by the pick motion inthe usual manner.

The builder arm 18 is provided at or near its free end with a projectionor lug 38 which extends laterally therefrom over the shifter arm 22.Hence when this lug 38 is in engagement with the top of the shifter armany downward movement imparted to the builder arm is likewise impartedto the shifter arm, but upward movement of the builder arm may takeplace independently of the shifter arm.

The shifter arm at its free end has pivoted thereto at 39 and upstandingtherefrom a latch 10 the upper end of which is shouldered as at 11 andd2 to engage the lower face 13 of the ladder or box rail 2 or otherfixed portion of the frame. A foot piece it is connected with the latch40 so that the operator by pressing his foot upon the foot piece ist mayswing the latch 10 forward to bring either the shoulder d1 or theshoulder &2 beneath the face 13; in the former case the parts are in theposition for doifing and in the latter case for the winding of thepreliminary traverses forming the preliminary winding of filling.Normally the latch 40 swings rearwardly by gravity against the stop 15into the position shown in dotted lines in Fig. 3. The latch is madeadjustable as to its length and for this purpose is shown as made in twoparts having their adjacent faces corrugated or roughened and lockedtogether by a set screw 46 extending through a longitudinal slot in oneor both parts.

In the operation of the spinning frame when it is desired to wind uponthe filling carrier a preliminary winding of filling as at the base ofthe slot of a feeler slotted bobbin the operator places his foot uponthe foot piece set and depresses the shifter lever 22-, which will thenswing independently about the shaft 23 until the latch swings forwardinto the position shown in full lines in Fig. 3, that is, with its facei2 beneath the face 43 of the ladder. Then the operator lets up with hisfoot leaving the latch and shifter lever in the position shown in Fig.3. The operator then brings the cam 1-1 to the position shown. in Fig.3, that is, with the side 21 of a lobe in contact with the follower 16near the peak of the lobe. It is desirable to have thecams so positionedthat the follower 16 will be as near to the peak of the lobeas it canand allow the passage of the peak of the cam over the follower todepress the shifter arm and builder arm sufliciently to release thelatch 40 from the face 43.

The winding operation will thus begin with an upward traverse, thefollower 16 on the builder arm 18 riding up on the side 21 of the lobeof the cam thus allowing the builder arm to swing upwardly about itspivot 19. But as the builder arm thus swings upwardly it carries with itthe pivot 23 of the shifter arm which now pivots about the pivotalconnection 39 with the latch. This gives aslight upward movement to thesheave 37 and consequently to the lifter rail and at the conclusion ofthe upward traverse the parts are in the position illustrated in Fig. 5.Thus substantially the entire amount of filling which would be laidduring an ordinary upward traverse is laid upon the filling carrier overa very small zone the limits of which are fixed by the comparativelysmall vertical movement of the sheave 37. In the continuation of theoperation of the machine a downward traverse follows being given by theside 20 of the next lobe of the cam let and during this movement theparts move from the position shown in Fig. 5 back to the position shown.in Fig. 3. During this movement the builder arm 18 swings downwardlyabout its pivot 19 giving a slight downward movement to the sheave 3'7until the projection 38 engages with the top of the shifter arm 22, andthen during the continued rotation of the cam let the builder arm andshifter arm are depressed together and when the peak of the cam passesthe follower 1.6 the latch i0 is released from the face l3 of the ladder2 and the latch swings to the position shown in dotted lines in Fig. 3.During this downward traverse the full amount of filling which would belaid in an ordinary traverse is laid but in substantially the samerestricted zone as that upon which the filling was laid in the firstupward traverse. Thus a preliminary winding of filling such as shown inFig. 2 is formed over a very narrow zone f? at the base of the feelerslot 48. Upon the continued operation of the machine, the latch l0 beingnow swung backwardly, the parts are in position for the main or servicetraverse and the winding proceeds as usual, the traverses nowlengthening out to that caused by the full swing of the builder arm, theshifter arm being held up against the projection 58 by the pull on thechain 12.

it the conclusion of the spinning and winding operation and when it isdesired to dofi the operator again places his foot upon the foot pieceis: and this time depresses the shifter arm ufficiently to enable theshoulder ll of the latch it) to come beneath the face and be heldthereby.

An adjustment such as that provided at .46 for the length of the latchl0 enables the point at which the first upward traverse shall begin tobe determined with accuracy.
